Yes you can do that, and yes you would need to buy a new sub. Only thing is you will need to cut the ends off one end of the speaker wire (unless your new AVR takes RCA ins). Doubt it since very few do.

Sorry to bump this old thread up, but my Spherex amp died and I want to keep the speakers if possible... I was thinking of buying a receiver and sub and hooking up the speakers to the new receiver. I'm considering just cutting the RCA plug off one end of each of the wires, but some of the rear wires are a bit short and I wouldn't mind replacing those... I'm not very good at soldering, so I was wondering if it's possible to buy speaker wire with RCA plugs already on one end?

Other option is to buy the Logitech Z5500 when it goes on sale again, or a cheap HTIB (need something with at least 2 optical inputs, or 1 HDMI input and an optical input). What do you guys think?

Not true if the impedance matches up and you know how to rig it up. Even if the impedance is off, could still rig it up to either cut the load in half or double it. If the speakers sound good, no reason to trash em.

The original speaker wire have RCA connectors. If I cut off one end, would it matter which is positive and negative wires to connect?

i believe it would, if you put the wrong polarity, you're speakers would be out of phase, and it'll sound like crap. If thats the case, i think it'll be very obvious. I don't know for sure because i've never tried.

I have been using the speakers with my old 5.1 Yamaha reciever for couple of yrs now. Bought new speaker wires and soldered the rca plugs.
I still have the amp/sub box and thinking of making into a sub. I think it will make a nice sub.

It's a weird issue. The amp turns on fine...and I can put on say..electronic music and it pounds hard. But you cant hear lyrics.

Same thing if I boot up my ps3. You can hear the menu music fine, albeit a little distorted, but you cant hear people talking...like the plate announcements in MLB 2k9.

I guess it's broken, and it's a shame because I absolutely love this system.
